You can prove a negative. First you determine all possible ways for it to be positive - then eliminate all of them.
This is why Atheists are full of it. They lack the tiniest minuscule faction of knowledge of everything yet claim with absolute certainty they know there is no God. There is noway they can KNOW that. It’s only their personal opinion based on belief with faith mankind will never find enough positive evidence to convince them God exists. Thus Atheism is a belief based on faith = a religion.
IMHO opinion Atheists do believe in God but are terrified of him - why else are they so emotional and hateful of something they do not believe in?
No you can’t prove a negative, because you can never find all the possible ways for it to be positive for elimination. There’s always some other possible way. Especially when your whole solipsism is based on the supernatural.
